Farming Systems to improve crop tolerance to frost - stubble rate locations
Aims

Determine thresholds of stubble loads (0, 1, 2 & 4t/ha) which increase severity and duration of frosts, and associated frost risks.

Key messages

The interim temperature results suggest that retaining 4t/ha of stubble significantly increases the severity and duration of frosts when compared to 0t/ha. On all occasions, reducing stubble loads to 0t/ha reduced the severity and duration.
